IMPROVEMENT INCONDENSERS FOR ILLUMINATING-GAS.

Specification forming part of Letters Patent No. 171,363, dated December 21, 1875; applicatiouled October 4, 1875.

thereby', and its action on the gas thus rendered more eiicient and uniform.

The invention relates to wheels having f spiral vanes, and arranged in the pipe leading from the retortto the puriiier, so as tobe revolved by the currentof gas without the intervention of any mechanical means orappliances for that purpose. The wheels are constructed exceedingly light, and their rotary action is Without the least perceptible retarding influence onr the ow of gas. The impact and rubbing action of the latter on the vanes ofthe wheels effect the desired condensation ofthe tar and other heavy matters, which are thrown off by centrifugal force-the rotations being ordinarily near two hundred per minute-and are thus collected in the pipe, and thereby conducted to 4 a suitable place for removal.

In the drawing, Figure l is a longitudinal section of a fragment ofthe pipe containing two of the wheels, and Fig. 2 a transverse section thereof. l

A is the pipe leading from the retort to the purifiers. '(Not shown.) 'Ihe Wheels B are constructed of radial fan-shaped spiral blades or vanes, and mounted on suitable axes in frames C. The arrangement of the same is transversely of the pipe A, and the vanes extend to the inner periphery thereof, their ends being joined by a dat ring, as shown, and thus held equidistant and rigid. The wheels are a cheap substitute for, and perform the function of, the coil .previously or commonly used to take up the heavy matters from gas by condensation of the same on its passage through them.

What I claim is- The Wheels B B, constructed With the radial spiral vanes, and arranged transversely within, and completely spanning the diameter of, the pipe leading from the retort to the puriers, as shown and described, to admit of their rotation by the force of the current of gas, as shown and described.
